Dear Vladyslav,
I have a problem with the use of the Schouten identity:
1) it exist, but it does not appear in the online manual
http://feyncalc.org/FeynCalcBook/
2) acting on a given expression A with Schouten[Calc[A]] is fine
(my expression is 0 after using Schouten, as it should),
but if I do SetOptions[Contract, Schouten -> True]
or SetOptions[Calc, Schouten -> True] (in practice Calc,
so SetOptions[Contract, Schouten -> True] should be enough),
my expression does not vanish without using Calc.
Why?
Thanks in advance for your help.
Best
Samuel Wallon
